The strength of the magnetic field between the poles of an electromagnet would be unchanged if :

The pole strength of a magnet is

The pole strength of a magnet is

How will you increase the strength of magnetic field in an electromagnet?

Define pole strength of magnet.

A small rod of bismuth is suspended freely between the poles of a strong electromagnet. It is found to arrange itself at right angles to the magnetic field. This observation establishes that bismuth is

The strength of magnetic field of an electromagnet is increased by inserting a core of ...............

State two ways by which the strength of magnetic field of an electromagnet can be increased.

The intensity of uniform magnetic field between poles of a magnetic is H. If a straight wire carrying current is placed in between the poles. The direction of force on the wire is-
